Technique: Nostril "Q" deformity is a common postoperative deformity in nasal alar reduction surgery, and there are no clinical reports on its correction. Based on the traditional Z-plasty technique, we designed an asymmetric Z-plasty technique to transfer the triangular mucosal flap inside the nasal cavity to the zone of notch deformity to correct the Q deformity.
Results: We included 12 patients in recent years in this study.

Objective: To validate the feasibility of an innovative nasal lining-framework complex (NLFC) for reconstructing total nasal defects.
Study Design: Retrospective cohort study.
Methods: This NLFC is composed of forearm flap and support framework.
Objective: The aim of this study was to investigate the dynamic expression of the SMAD family during guided bone regeneration for the reconstruction of cranio-maxillofacial bone defects.
Methods: A swine model of guided bone regeneration was established with one side of the rib as the trauma group and the contralateral as control group. Periosteal and regenerative tissue specimens were harvested at 9 time points in the early, middle, and late phases, and were subjected to gene sequencing and tissue staining.
Summary: Nasal reconstruction in pediatric patient is very challenging and it requires consideration of later nasal development. Herein, we introduce an innovative preauricular free flap pedicled with retrograde vascular (PFFPRV) for pediatric nasal reconstruction. In this PFFPRV technique, the retrograde superficial temporal vessels were used as the flap pedicle.

Protein arginine methyltransferase 5 (PRMT5), an enzyme that catalyzes symmetric and asymmetric methylation on arginine residues of histone and non-histone proteins, is overexpressed in many cancers. However, whether or not PRMT5 participates in the regulation of ESCC remains largely unclear.

In this study, the immunologic properties of dermal BMPR-IB+ subpopulation before and after osteogenic differentiation were reported. The results confirmed that dermal BMPR-IB+ cells possessed a similar osteogenic differentiation potential with bone marrow mesenchymal stromal cells in a mouse model.

Related studies were identified from PubMed, EMBASE, Springer Link, Ovid, Chinese Wanfang Data Knowledge Service Platform, Chinese National Knowledge Infrastructure (CNKI), and Chinese Biology Medicine (CBM). Pooled ORs and 95% CIs were used to assess the strengthof the associations.
